Localization of expression of an NCR in Medicago nodules.
A, GUS staining of a nodule section with the MtTC100321_s_at promoter:GUS construct. B, Detection of the antisense probe corresponding to MtTC100321_s_at in a 10-µm thick nodule section. C, Magnification of boxed area in B. Bars in A and B are 200 µm. Bar in C is 100 µm. I, meristematic zone; II, infection zone; II-III, intermediate zone; III, nitrogen fixation zone of the nodule. All nodules were harvested at 14 dpi with Sm1021.
